MetabolomicsWe characterize the anti-phage function of a type IV TA system, ShosTA toxin-antitoxin system provides phage defense via DNA damage and repair
Widespread in bacteria and archaea, Toxin-antitoxin (TA) systems have been recently demonstrated to function in phage defense. Here we characterize the anti-phage function of a type IV TA system, ShosTA. Using structural and biochemical approaches, we show that ShosT couples phosphoribosyltransferas...

MetabolomicsPlasmid-encoded toxin defence mediates mutualistic microbial interactions

Gut environments harbour dense microbial ecosystems in which plasmids are widely distributed. Plasmids facilitate the exchange of genetic material among microorganisms while enabling the transfer of a diverse array of accessory functions. However, their precise impact on microbial community compo...

MetabolomicsBlocking Toxin function and Modulating Gut Microbiota: Caffeic Acid and its Derivatives as Potential Treatments for Clostridioides difficile Infections

Clostridioides difficile infection (CDI) is the leading cause of hospital-acquired diarrhea that seriously threaten public health. Disruption of normal gut microbiota by the use of broad-spectrum antimicrobial agents enables C. difficile to proliferate in the colon. The emergence and prevalence o...

MetabolomicsAntibacterial Monoclonal Antibodies Do Not Disrupt the Intestinal Microbiome or Its Function
Antibiotics revolutionized medicine, however, it is now clear that broad-spectrum antibiotics alter the composition and function of the host’s microbiome. The microbiome plays a key role in human health and its perturbation is increasingly recognized as contributing to many human diseases. Wide spre...

MetabolomicsGlycosylation-mediated detoxification of zearalenone by the Tibetan yeast Hannaella zeae: Multi-omics insights into its dual-function mechanism

This study investigated the detoxification of zearalenone (ZEN) by the Tibetan Plateau yeast Hannaella zeae via untargeted LC-MS/MS-based metabolomics. H. zeae was cultured in NYDB medium with ZEN supplementation, and samples were harvested after 36 h of incubation for metabolomic analysis. The c...

TranscriptomicsTranscription profiling of human HeLa cells treated with major listerial toxin listeriolysin
Upon infection, pathogens reprogram host gene expression. In eukaryotic cells, genetic reprogramming is induced by the concerted activation/repression of transcription factors and various histone modifications that control DNA accessibility in chromatin. We report here that the bacterial pathogen, ...

ProteomicsShiga toxin-positive extracellular vesicles induce higher mortality and more kidney injury than free toxin
Escherichia coli O157:H7 is a non-invasive Shiga toxin (Stx)-producing pathogen that causes gastroenteritis and hemolytic uremic syndrome characterized by acute kidney injury. Stx binding to cells induces release of extracellular vesicles (EVs) containing the toxin. This study aimed to demonstrate t...
